Security Features

OTP Authentication

For sensitive data, enable OTP authentication:

1. Setup OTP: Use setup_otp tool to generate QR code and backup codes

2. Verify Access: Use verify_otp tool before accessing encrypted data

3. Check Status: Use otp_status tool to see current authentication state

4. Lock Session: Use lock_otp tool to immediately terminate access when stepping away

Encryption

• AES-256 encryption for file contents

• Stable encryption keys (not time-based)

• OTP used for access control, not key derivation
